Fan racing intermittently, no CPU load, Thinkpad Yoga 15

I just purchased a Thinkpad Yoga 15. I was trying to fix its disabled discrete graphics card. One thing i did was update the BIOS. I think it's after this that the fan started to intermittently race. It's silence, then runs loudly and annoyingly for a second or two, slilent again, then randomly continues. Before the upgrade it was silent all the time.
This is terrible. Anyone has any ideas?

But now TpFan works all the time, though only in smart mode, and when I plug in the power to stream a video the computer doesn't reach boiling point and then shut down.Interesting. My fan diagnostic comes up as unavailable...

CPU load LOW - Fan speed HIGH - WHY ?

Hi
I'm watching youtube videos on my mac - under Windows XP (bootcamp) - I'm monitoring my CPU usage while watching the videos because my fan is spinning at full speed - yet the CPU is not working hard - about 5 to 10%. Does anyone know why the computer is getting hot and fans spinning faster if CPU load is still very low? Is it possible that I only see one of the cores in the windows monitoring system? I press control alt delete to access the info.
Any suggestions would be helpfull
Thanks

Hi tcdm1972,
A lot of postsfrom fellow users report their fan kicking out loud mostly when watching or using application that related with video or streaming video.
I'm not an apple tech, so I guess that fan also try to cool down the GPU chip sets since it is dinamically adjusted in and out of allocated memory and rendering or streaming video to the screen and become hot as well. (I could be wrong).
And most of the time the fan kicking when macbook plugged with mag safe (processor runs optimal clock speed).
Hope other user have different opinion.
Good Luck.

Thinkpad Yoga 12 20CD extreme fan noise

Hi,
Last week, I had my Thinkpad Yoga 12 serviced, as it didn't boot anymore. The whole interior got replaced. Since then, the fan noise is really unbearable. It was the same when I initially bought the machine, but then, a BIOS update (don't know which anymore) fixed it. It's a loud high-pitch noise, like a whissle.
I need urgent help, my collegues are complaining of the noise.
Best regards,
Jeroen

Fan RPM (rounds per minute) based on CPU load

I did some small testings regarding when the fan's are starting. I'm experiencing the following:
When running 3 times: yes > /dev/null the fans start to spin up after 1 minute full CPU load. They keep running till i kill those 3 processes. After 10 minutes full load the notebook is getting less hot because the fans are running at a good speed.
What they should do is write a component in osx that will measure the temperature and based on that information let the fans run...
With the current system the load is increasing all the time because you use it.. if the fans would start when its getting hotter the increasing temperature would stop and the case temp would be stable.
Therefor i dont think bringing in your laptop will help. I think they should be able to fix the problem thru software. Just like the whine issue... just the wrong amount of voltage are send thru the cpu.
The problem is... apple doesnt confirm this.. i hope OSX 1.4.7 will have such a tooling within it.
What do you think?

My completely unscientific experiences with my own MBP seems to support this, and I do believe that it begun happening after the last SMC update. I also believe that heat does in fact have an effect on the fans, but it is additive and that is why you mostly experience the fan activity generated by the CPU load.
I can hear my fans quite clearly on low RPM because of a strange, plastic whirring sound (oddly enough, they become more quiet on higher RPMs).

Thinkpad Yoga - fan sounds like a plane

In tablet mode (and mostly when the tablet is horizontal) then the fan (I suppose it is the fan) makes some horrible noise. I can't work with it at work in this mode as my colleagues look at me weirdly. When I lift up the screen a bit, then the fan stops in a struggling sound.
I did a video of the issue:
https://www.youtube.com/watch?v=e0Y0hEr3qKc
It's a shame because in latpop mode it doesn't make any sound, even thought the work I do in laptop mode is much more intensive. Would not be for the sound, this is the best laptop I ever had. The keyboard is great, the edges are not sharp, the screen is beautiful, the wacom pen works perfectly. An awesome computer.
Anyone one had this fan noise issue?

Hi,
Welcome to Lenovo Community Forums!
I’m sorry to hear that fan in your Lenovo ThinkPad Yoga is making noise.
If your laptop feels hot and shows any of the problems below, chances are its overheating or getting there:
Fan constantly running and making loud whirring noises
Computer struggling to perform basic tasks like opening a new browser window
Mysterious error messages popping up in random programs
Lines on your laptop screen (a sign your video card is overheating)
System freezing or the dreaded BSOD (blue screen of death)
The laptop abruptly shuts down on its own
First of all, update BIOS to the latest version.
Use dust remover spray to clean out of the laptop's vents. Dust can accumulate in and block the laptop's fan vents. Start using compatible cooling pads which will help in the flow of cool air into the underside vents of the laptop. Keep your working environment or computer room as comfortably cool as possible. Check if the fan is touching some wires during spinning to cause the noise.
Best Regards,
Mithun.

(Linux, SL510, NSLDEGE) No processes, 100% CPU-load reboot 1% CPU-load

I have a very big problem:
I bought a Lenovo ThinkPad SL510 NSLDEGE (2847-DEG) on this (german) website with no installed operating system. At first, I installed Ubuntu GNU/Linux 10.04 which worked excellently at the first view.
But then the big problem appeared the first time: suddenly my CPU-load grew from ca. 3% to 100% (because I started an editor or I opened a new firefox-tab) and I couldn't use my ThinkPad in any way, until the system crashed and I had to reboot. After the reboot all worked fine.
This problem appeares intermittent and I always see my last chance in rebooting the entire operating system. I've already tried different Linux-Distributions, but this did not solve my problem. And I've already tested my random access memory (RAM) with Memtest86.
Thus, my question is: Do you have an idea, what could cause this problem? What could be the reason for my CPU-crashes?
Greetings, Mekeor

I'm sure that this is not a Linux-problem!
Furthermore I wrote a bug report on launchpad (the ubuntu bug-report-website) here: https://bugs.launchpad.net/ubuntu/+bug/615792 . And here is my first forum-entry in the german ubuntu-forums (forum.ubuntuusers.de).
Besides this phenomenon, I think, is a specific characteristic of my Model (SL510, NSLDEGE)!

Macbook Pro fan running constantly and CPU running slow

So, I have a Macbook Pro 2010 2.3 i7 that has started running really slow and the fan is running constantly.
In activity monitor it shows a kernel_task running constantly at around or above 200%.
I have tried all the regular tasks. PRam reset, SMC reset and nothing seems to fix it.
I have also tried a system reinstall to no avail.
Maybe I'm on the wrong track, but from what I have read, the kernel_task might be trying to slow my CPU down because it thinks it is being overworked?
Maybe the fans are also being activated because it thinks the computer is too hot?
Anyway, if anyone has any idea as to what I can do to figure out what is going on, let me know. Thanks

Kernel_task running above 500% CPU load on my Macbook Pro running OSX 10.9.4

I recently upgrade my Macbook Pro to OSX 9.0.4 and the system is running sluggishly slow, Activity Monitor showing kernel_task always running above 500% CPU load, system fan always running loud at startup but laptop is not overheating. Below is the EtreCheck report, hoping if anyone can help me fix this issue, much appreciate it. Btw, I have done the SMC reset, but nothing has helped.

The kernel is using excessive processor cycles. Below are some possible causes for the condition.
Throttling
When it gets high temperature readings from the hardware, or a low-voltage reading from the battery, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
☞ a buildup of dust on the logic board
☞ high ambient temperature
☞ a worn-out or faulty battery in a portable
☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on battery power, the fault is in the battery or the logic board. If it happens only on AC power, charging is causing the machine to heat up. That may be normal on some models. CPU usage should drop when charging is complete.
Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
Corrupt NVRAM or SMC data
Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
External display
Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.

Thinkpad Yoga 13 keyboard and mousepad don't work

Hello people!
Last time I went to US, I've bought this machine from Amazon: Lenovo ThinkPad Yoga Signature Edition - 12.5" 2-in-1 Touchscreen Notebook PC - Intel i5 Haswell / 8GB RAM / 128GB SSD / WiFi / Webcam / Windows 8.1 - Black
I love it! At least until two weeks ago... after a windows/lenovo update things starts to be really hard.
My keyboard and mousepad simple don't work anymore, totally unresponsive. If I hit "del" to access the bios, the keyboard does work, after that, when windows is loading and fully loaded, I've got only the "tablet" mode.
The only thing that works correctly is the touchscreen, as it only recognize itself as a tablet, not as a ultrabook. The screen also rotates automatacly when windows is fully loaded, so I have to use the tent mode with an external usb keyboard/mouse or type in the screen keyboard...
I leave in Brazil, got in contact with lenovo suport team here, after a lot of procedures, that didn't solve the problem, they told me to get in contact with lenovo US and ask for an original dvd recovery.
Is there anyone with a different approach to solve this problem?

First try SMC and PRAM resets:

If no success, make an appointment at an Apple store genius bar for a free diagnosis.

Display won't work and fans racing G5 and Apple display

I have a G5 tower with an Apple display connected using a DVI to ADC adaptor.
I have just moved house and now the display doen't power up. The computer starts up and plays its start sound but no life from the screen. The light in the start button on the display lights up when pressed, but goes out when the button is released.
After a while, the fans in the tower unit start racing.
Help!

Hi, Fans racing is normal if no OS loads to handle them.
I'd open it & carefully reseat the Video card for a start.

Thinkpad Yoga Hot

So, recently I've noticed something odd about my Thinkpad Yoga S1. I close the lid and put my computer away. Usually when I take it out, it has started to hibernate but today when I took out my computer, I noticed that it was quite warm and it was still running when I opened it up. I checked my power settings and everything is the same. WHat is going on?

Do any of you have Kaspersky Anti-Virus or Internet Security? Seems like few T540 owners also got the same problem and one of them discovered it is Kaspersky causing the problem. I can comform it too.
I am using Kaspersky Internet Secuirty 2015, when I resume my TPY from sleep, the message receiver for shortcut hot keys will show up and use 20-35% processing power which cause the laptop to heat up.
I hope a Thinkpad rep can come in to report the bug.

Thanks ChrisL_US! I do have kaspersky anti-virus 2015 installed.

Too high cpu load with HP 6510b

Hello guys,
I have a very high cpu load on my laptop even if nothing despite htop is running. I guess it's a problem with acpi because when I deactivate acpi completely over the bootline I have no such problems.
How could I fix that?
Thank you in advance.

Hello B,
unluckily noacpi doesn't help but acpi=off. That seems to be the only way to stop the high load.
Is there any patched acpi or something else?
I also think I picked the bad revision with fan problems and some more...

Cpu load at half 100c

With my mac at 45 percent cpu load my mac will hit 100c on left for dead 2 before it has the time to speed up the fans, when the fans speed up it will lower it to 92-98c is this normal

Try a SMC reset:

No download for ThinkPad Yoga 12 dependency package 1.6.32.00?

Our ThinkPad Yoga 12 OEM boxes (also X1 Carbon Gen 3) have dependency package 1.6.32.00 pre-installed (i assume it is for Lenovo Support & Lenovo Companion Metro apps).
we are trying to rebuild enterprise loads, but in the support website, the only one that can be downloaded is a old version 1.6.28.0 (2014/08/14) for older models ThinkPad Yoga , Yoga 11e, X1C, X1C Gen 2 from http://support.lenovo.com/en/downloads/ds034404
It is not listed in model 20DK device matrix download page either (only settings dependency package for Lenovo Settings Metro app) http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-yoga-series-laptops/thinkpad-...
is it located in another place? or we have to call enterprise support to get it?
Solved!

How does the new i7 Mini behave under high CPU load?

Did anybody test a new quad-core i7 under high CPU load, using all cores at 100% during more than 15 minutes?
How does it behave (from a thermal point of view)?
Is the fan loud under such load?
Does it get as hot as a Macbook Air?
Do it feels like you're pushing it above its design goals, or does it look well suited for 100% CPU on all cores?
Thanks!!
